reading characters

Hi,

I am having some problems with my code. I am trying to read characters from scanf. What happens is that it doesnot read the whole character it read only 1 character. I tried making a loop but it keeps giving me errors.

Code:

---

#include <stdio.h>
#include <stdlib.h>

int main()
{
        char c;
        float i;
        int number;
        float f =50;


        scanf("%c", &c);

        number = atoi(c);

        i=f+(float)number;

        printf("%f",i  );

        return 0;
}

---

atoi takes a string, not a single character, and scanf with %c only reads a single character

You need something like

Code:

---

char c[10];
fgets( c, sizeof c, stdin );
number = atoi(c);

---

the thing is that we are only allowed to use scanf and we have to use characters.

Code:

---

char c[10];

scanf("%s", c);

---

If your teacher isn't letting you use strings, then this is just a bad assignment.

It's easier to scanf an int to begin with:

Code:

---

#include <stdio.h>

int main(void)
{
    int number;

    printf("Please give an integer and press enter: ");

    /* read a number from the keyboard and assign it to 'number' */
    scanf("%d", &number);

    printf("You gave %d\n", number);
}

---

I think the idea of the program was to convert from a character to an integer to a float.

I am able to do it with strings. but the problem is that the teacher wants us to read character and then we have to convert all those character to floats so I can do some computations.

Code:

---

char string[9] = { 0 };
float f;

scanf("%c%c%c%c%c%c%c%c", string[0], string[1], string[2], string[3], string[4], string[5], string[6], string[7]);
sscanf(string, "%f", &f);

hehehehe

fgets(). :)

thanks guys I used fgets since the way my prof is saying it doesnot make sense.Thanks alot.
